muted-users: Say "Muted user" to replace a user's name, where applicable

chrisbobbe · sm-sayedi · chrisbobbe · commit 58fc6c698c31 · 2025-06-12T11:57:09.000-07:00
(Done by adding an is-muted condition in store.userDisplayName and store.senderDisplayName, with an opt-out param.) If Chris is muted, we'll now show "Muted user" where before we would show "Chris Bobbe", in the following places: - Message-list page: - DM-narrow app bar. - DM recipient headers. - The sender row on messages. This and message content will get more treatment in a separate commit. - Emoji-reaction chips on messages. - Typing indicators ("Muted user is typing…"), but we'll be excluding muted users, coming up in a separate commit. - Voter names in poll messages. - DM items in the Inbox page. (Messages from muted users are automatically marked as read, but they can end up in the inbox if you un-mark them as read.) - The new-DM sheet, but we'll be excluding muted users, coming up in a separate commit. - @-mention autocomplete, but we'll be excluding muted users, coming up in a separate commit. - Items in the Direct messages ("recent DMs") page. We'll be excluding DMs where everyone is muted, coming up in a separate commit. - User items in custom profile fields. We *don't* do this replacement in the following places, i.e., we'll still show "Chris Bobbe" if Chris is muted: - Sender name in the header of the lightbox page. (This follows web.) - The "hint text" for the compose box in a DM narrow: it will still say "Message @chris Bobbe", not "Message @muted user". (This follows web.) - The user's name at the top of the Profile page. - We won't generate malformed @-mention syntax like @_**Muted user|13313**.
